User Manual13Install and Access the Switch in
Your Network
Gigabit Ethernet Plus Switches

Access the switch and discover the IP address of the switch

By default, the switch receives an IP address from a DHCP server (or a router that functions as a DHCP server) in your network.
For information about setting up a fixed (static) IP address on the switch, see Set up a fixed IP address for the switch on page 15.

Access the switch from a Mac or Windows-based computer using the NETGEAR Switch Discovery Tool

The NETGEAR Switch Discovery Tool (NSDT) lets you discover the switch in your network and access the device UI of the switch from a Mac or a Windows-based computer.
To install the NSDT, discover the switch in your network, access the switch, and discover the switch IP address:
1. Download the NSDT by visiting netgear.com/support/product/netgear-switch-discovery-tool.aspx.
Download either the Mac or Windows version.
2.
Temporarily disable the firewall, Internet security, antivirus programs, or all of these on the computer that you will use to configure the switch.
3.
Unzip the NSDT files, double-click the .exe or .dmg file (for example,
NETGEAR+Switch+Discovery+Tool+Setup+1.2.102.exe or NetgearSDT-V1.2.102.dmg), and install the program on your computer.
Depending on your computer setup, the installation process might add the NETGEAR Switch Discovery Tool icon to the dock of your Mac or the desktop of your
Windows-based computer.
4. Reenable the security services on your computer.
5. Power on the switch. The DHCP server assigns the switch an IP address.
6. Connect your computer to the same network as the switch. You can use a WiFi or wired connection. The computer and the switch must be on

Tip: You can copy and paste the IP address into a new shortcut or bookmark it for quick access on your computer or mobile device. However, if you restart the switch, a dynamic IP address (assigned by a DHCP server) might change the IP address, and the bookmark might no longer link to the login page for the switch. When you restart the switch, you must repeat this procedure so that you can discover the new IP address of the switch in the network and update your bookmark accordingly. You can also set up a fixed (static) IP address for the switch (see Set up a fixed IP address for the switch on page 15 ) to make sure that the new bookmark always links to the login page for the switch, even after you restart the switch.

Set up a fixed IP address for the switch

By default, the switch receives an IP address from a DHCP server (or a router that functions as a DHCP server) in your network. However, the DHCP server might not always issue the same IP address to the switch. For easy access to the switch device UI, you can
Your Network
User Manual15Install and Access the Switch in
Gigabit Ethernet Plus Switches
set up a fixed (static) IP address on the switch. This allows you to manage the switch anytime from a mobile device because the switch IP address remains the same.
To change the IP address of the switch, you can connect to the switch by one of the following methods:
Through a network connection. If the switch and your computer are connected to
• the same network (which is the most likely situation), you can change the IP address
of the switch through a network connection (see Set up a fixed IP address for the switch through a network connection on page 16).
Through a direct connection. In the unlikely situation that the switch is not connected
• to a network, or for some reason you cannot connect to the switch over a network
connection, you can change the IP address of the switch by using an Ethernet cable and making a direct connection to the switch (see Set up a fixed IP address for the switch by connecting directly to the switch off-network on page 17).

Set up a fixed IP address for the switch through a network connection

If the switch and your computer are connected to the same network (which is the most the likely situation), you can change the IP address of the switch through a network connection.

802.1P/DSCP QoS mode. Applies pass-through prioritization that is based on
• tagged packets and lets you set rate limits for incoming and outgoing traffic for individual ports. If broadcast filtering is enabled, you can also set the storm control rate for incoming traffic for individual ports. This QoS mode applies only to devices that support 802.1P and Differentiated Services Code Point (DSCP) tagging. For devices that do not support 802.1P and DSCP tagging, ports are not prioritized but the configured rate limit is still applied.
You can limit the rate of incoming traffic, outgoing traffic, or both on a port to prevent the port (and the device that is attached to it) from taking up too much bandwidth on the switch. Rate limiting, which you can set for individual ports in either QoS mode, simply means that the switch slows down all traffic on a port so that traffic does not exceed the limit that you set for that port. If you set the rate limit on a port too low, you might, for example, see degraded video stream quality, sluggish response times during online activity, and other problems.

Use port-based quality of service and set port priorities

802.1P/DSCP is the default QoS mode on the switch, but you can also set port-based
QoS. For each port, you can set the priority and the rate limits for both incoming and outgoing traffic:
Port priority. The switch services traffic from ports with a critical priority before traffic
• from ports with a high, medium, or low priority. Similarly, the switch services traffic from ports with a high priority before traffic from ports with a medium or low priority. If severe network congestion occurs, the switch might drop packets with a low priority.
Port rate limits. The switch accepts traffic on a port at the rate (the speed of the
• data transfer) that you set for incoming traffic on that port. The switch transmits traffic from a port at the rate that you set for outgoing traffic on that port. You can select each rate limit as a predefined data transfer threshold from 512 Kbps to 512 Mbps.

Use 802.1P/DSCP quality of service

In the 802.1P/DSCP QoS mode, the switch uses the 802.1P or DSCP information in the header of an incoming packet to prioritize the packet. With this type of QoS, you cannot control the port prioritization on the switch because the device that sends the traffic (that is, the packets) to the switch prioritizes the traffic. However, you can set the rate limits for individual ports on the switch.
The switch accepts traffic on a port at the rate (the speed of the data transfer) that you set for incoming traffic on that port. The switch transmits traffic from a port at the rate that you set for outgoing traffic on that port. You can select each rate limit as a predefined data transfer threshold from 512 Kbps to 512 Mbps.

Manage broadcast filtering and set port storm control rate limits

A broadcast storm is a massive transmission of broadcast packets that are forwarded to every port on the switch. If they are not blocked, broadcast storm packets can delay or halt the transmission of other data and cause problems. However, you can block broadcast storms on the switch.
You can also set storm control rate limits for each port. Storm control measures the incoming broadcast, multicast, and unknown unicast frame rates separately on each port, and discards the frames if the rate that you set for the port is exceeded. By default, no storm control rate limit is set for a port. You can select each storm control rate limit as a predefined data transfer threshold from 512 Kbps to 512 Mbps.

VLAN overview

Virtual LANs (VLANs) are made up of networked devices that are grouped logically into separate networks. You can group ports on a switch to create a virtual network made up of the devices connected to the ports.
You can group ports in VLANs using either port-based or 802.1Q criteria:
Port-based VLANs. Assign ports to virtual networks. Ports with the same VLAN ID
• are placed in the same VLAN. This feature provides an easy way to partition a network into private subnetworks.
If the switch is the only switch in your network and you do not need a VLAN to function across multiple network devices (such as a router, another switch, a WiFi AP, or any network device that supports VLANs), we recommend that you use a port-based VLAN. If you need a single VLAN on a single port (other than the uplink port), use the basic port-based VLAN configuration. If you need multiple VLANs on a single port, use the advanced port-based VLAN configuration. The switch supports the following port-based VLAN modes:
-
Basic Port-Based VLAN. In a basic port-based VLAN configuration, ports with the same VLAN ID are placed into the same VLAN. Except for the uplink port, you can assign each port to a single VLAN only. The number of VLANs is limited to the number of ports on the switch.
-
Advanced Port-Based VLAN. In an advanced port-based VLAN configuration, ports with the same VLAN ID are also placed into the same VLAN, but you can assign a single port to multiple VLANs.
802.1Q VLANs. Create virtual networks using the IEEE 802.1Q standard. 802.1Q
• uses a VLAN tagging system to determine which VLAN an Ethernet frame belongs to. To use an 802.1Q VLAN that is set up on another device, you must know the VLAN ID.
If you need a VLAN to function across multiple network devices (such as a router, another switch, a WiFi AP, or any network device that supports VLANs), we recommend that you use an 802.1Q VLAN. If you do not need to customize tagging on a single port and you do not need a voice VLAN, use the basic 802.1Q VLAN configuration. If you do need to customize tagging on a single port or you do need a voice VLAN, use the advanced 802.1Q VLAN configuration. The switch supports the following 802.1Q VLAN modes:
-
Basic 802.1Q VLAN. In a basic 802.1Q VLAN configuration, VLAN 1 is added to the switch and all ports (1 through 5 for the GS305EP or GS305EPP, and 1 through 8 for the GS308EP or GS308EPP) function in access mode as members of VLAN

Gigabit Ethernet Plus Switches
mode can belong to a single VLAN only and does not tag the traffic that it processes. A port that functions in trunk mode automatically belongs to all VLANs on the switch and tags the traffic that it processes.
-
Advanced 802.1Q VLAN. In an advanced 802.1Q VLAN configuration, VLAN 1 is added to the switch and all ports (1 through 5 for the GS305EP or GS305EPP, and 1 through 8 for the GS308EP or GS308EPP) are untagged members of VLAN 1. You can tag ports, untag ports, exclude ports, add more VLANs, assign a different VLAN to a port, manage port PVIDs, and manage a voice VLAN.

Manage basic 802.1Q VLANs

In a basic 802.1Q VLAN configuration, VLAN 1 is added to the switch and all ports function in access mode as members of VLAN 1. You can change the mode for a port to trunk mode, you can add more VLANs, and you can assign a different VLAN to a port.
After you activate the Basic 802.1Q VLAN mode, you can create VLANs, assign the VLANs to ports that function in access mode, and assign the trunk mode, which carries traffic for all VLANs.

Assign the port mode in a basic 802.1Q VLAN configuration

In an 802.1Q VLAN configuration, you can assign one of the following port modes:
Access mode. A port that functions in access mode can belong to a single VLAN
• only and does not tag the traffic that it processes. You would typically use access mode for a port that is connected to an end device such as a gaming device, media device, or computer. When a port that functions in access mode receives data that is untagged, the data is delivered normally. When a port that functions in access mode receives data that is tagged for a VLAN other than the one the port belongs to, the data is discarded.
Trunk mode. A port that functions in trunk mode automatically belongs to all VLANs
• on the switch and tags the traffic that it processes. You would typically use trunk mode for a port that is connected to another network device. For example, you would assign trunk mode for an uplink to another switch or router and for a downlink to a WiFi access point.

Set an existing advanced 802.1Q VLAN as the voice VLAN and adjust the CoS value

The switch can support a single advanced 802.1Q VLAN as the voice VLAN to facilitate voice over IP (VoIP) traffic. Because a voice VLAN might require a single port to join to multiple VLANs as an untagged member, you can set up a voice VLAN only as an advanced 802.1Q VLAN. For information about creating an advanced 802.1Q VLAN, see Create an advanced 802.1Q VLAN on page 48.
A port that is a member of the voice VLAN sends all its voice packets through the voice VLAN but other types of packets (for example, data packets) that come in on the port are forwarding according to the PVID setting on the port.
The default Class of Service (CoS) value for the voice VLAN is 6, which you can adjust to any value from 0 (the lowest priority) to 7 (the highest priority). The voice VLAN CoS value applies to all traffic on the voice VLAN. You can set the default VLAN (VLAN 1) as the voice VLAN.

Set up static link aggregation

Static link aggregation on the switch allows you to combine multiple Ethernet ports into a single logical link. Your network devices treat the aggregation as if it were a single link. Depending on how link aggregation is set up in your network, the link supports either increased bandwidth (a larger pipe) or fault tolerance (if one port fails, another one takes over).
The GS305EP and GS305EPP switches each support a single static link aggregation group (LAG) with up to four ports.
The GS308EP and GS308EPP switches each support two static LAGs with up to four ports each. That means that one static LAG can support a link of up to 4 Gbps.
User Manual58Manage the Switch in Your
Network
Gigabit Ethernet Plus Switches
Note: The switch does not support Link Aggregation Control Protocol (LACP).
You set up static link aggregation on the switch through a LAG in the following order:
1. Set up the LAG on the switch (see Set up a link aggregation group on page 59).
2.
Connect the ports that must be members of the LAG on the switch to the ports that must be members of the LAG on another device in your network (see Make a link aggregation connection on page 60).
3. Enable the LAG on the switch (see Enable a link aggregation group on page 60) and on the other device.

Set up a link aggregation group

You set up static link aggregation on the switch by adding ports to a link aggregation group (LAG), and by enabling the LAG. However, for a LAG to take effect, you first must make sure that all ports that participate in the LAG (that is, the ports on both devices) use the same speed, duplex mode, and flow control setting (see Manage individual port settings on page 26 for information about changing these settings on the switch), and you must set up a physical link aggregation connection (see Make a link aggregation connection on page 60).
After you set up a link aggregation group and make a physical link aggregation connection, you can enable the link aggregation group (see Enable a link aggregation group on page 60).
To set up one or more link aggregation groups on the switch:
1.
Open a web browser from a computer that is connected to the same network as the switch, or connected directly to the switch through an Ethernet cable.
2. Enter the IP address that is assigned to the switch. A login window opens.

A LAG must consist of at least two ports, but can consist of all ports.
The number of LAGs that the switch supports depends on the model.
7. Click the APPLY button. Your settings are saved.

Make a link aggregation connection

Before you make a physical link aggregation connection to another network device (usually a router or another switch) that also supports link aggregation, you must first set up a LAG on the switch (see Set up a link aggregation group on page 59). If you do not, the LAG cannot take effect. Whether a LAG on the switch functions to support increased bandwidth or fault tolerance depends on the LAG configuration on the other network device.
All ports that participate in a LAG (that is, the ports on both devices) must use the same speed, full duplex mode, and flow control setting. For information about changing these settings on the switch, see Manage individual port settings on page 26.
To make link aggregation connections between the switch and another network device:
Using Ethernet cables, connect each port that must be a member of the LAG on the switch to each port that must be a member of the same LAG on another network device.
The port numbers on the other network device do not matter as long as:
The ports on the other network device are members of the same LAG.
The LAG consists of the same total number of ports.
The ports use the same speed, full duplex mode, and flow control setting as the
ports in the LAG on the switch.

Enable a link aggregation group

After you set up a link aggregation group (see Set up a link aggregation group on page
59) and make a physical link aggregation connection (see Make a link aggregation
connection on page 60), you can enable the link aggregation group.
Note: You must also enable the LAG on the other network device.

Manage multicast

Multicast IP traffic is traffic that is destined to a host group. Host groups are identified by Class D IP addresses, which range from 224.0.0.0 to 239.255.255.255.
Internet Group Management Protocol (IGMP) snooping allows the switch to forward multicast traffic intelligently. Based on the IGMP query and report messages, the switch forwards traffic only to the ports that request multicast traffic, rather than to all ports, which could affect network performance.
IGMP snooping helps to optimize multicast performance and is especially useful for bandwidth-intensive IP multicast applications such as online media streaming applications.

PoE considerations for switches that support PoE

A switch that supports Power over Ethernet (PoE) prioritizes the PoE power that it supplies in ascending port order (that is, from the lowest-numbered port to the highest-numbered port), up to its total power budget. If the power requirements for the attached powered devices (PDs) exceed the total power budget of the switch, the PD on the highest-numbered port is disabled to make sure that the PDs that are connected to the higher-priority, lower numbered ports are supported first.
Just because a PD is listed as an 802.3at PoE powered device does not necessarily mean that it requires the maximum power limit of the specification. Many PDs require less power, allowing all PoE ports to be active simultaneously.
The following table describes the PoE classes and the PoE power that a switch allocates.
Table 5. PoE classes and PoE power allocations
Class DescriptionStandardDevice Class

Manage the PoE ports

You can turn the port on the switch on and off by using the device UI.
To power cycle the PoE ports through the device UI:
1.
Open a web browser from a computer that is connected to the same network as the switch, or connected directly to the switch through an Ethernet cable.
2. Enter the IP address that is assigned to the switch. A login window opens.
User Manual80Maintain and Monitor the Switch
Gigabit Ethernet Plus Switches
3. Enter the device management password. The password is the one that you specified the first time that you logged in. The
password is case-sensitive.
The HOME page displays.
4. Select POE. The Power over Ethernet (PoE) page displays.
5.
To enable or disable the uninterrupted PoE feature, click the Uninterrupted POE button:
Disabled: The button bar displays gray and the button is positioned on the left.
Enabled: The button bar displays green and the button is positioned on the right.
By default, the uninterrupted PoE feature is disabled, causing the switch to stop providing PoE power while it is rebooting. If you enable the uninterrupted PoE feature, the switch continues to provide PoE power to any attached PDs while the switch is rebooting, even if it is rebooting after a regular firmware update.
However, note the following situations during which the switch temporarily stops providing PoE:
The switch reboots because you reset it to factory default settings.
The switch reboots because you upgrade the switch firmware with a change in
the configuration structure, an update to the chip driver, or a change to the default PoE settings.
6.
On the SETTING menu, open the menu for the port number. The port settings display.
7. Click the EDIT button.
8.
From the Port Power menu, select one of the following options:
Enable: The port’s capacity to deliver power is enabled. This is the default setting.
Disable: The port’s capacity to deliver power is disabled.
9.
From the Port Priority menu, select the priority for the port in relation to other ports if the total power that the switch is capable of delivering exceeds the total power budget:
Low: Low priority. This is the default setting.
High: High priority.
Critical: Critical priority.
User Manual81Maintain and Monitor the Switch
Gigabit Ethernet Plus Switches
The port priority determines which ports can still deliver power after the total power delivered by the switch exceeds the total power budget. (In such a situation, the switch might not be able to deliver power to all connected devices.) If the same priority applies to two ports, the lower-numbered port receives higher priority.
10.
From the Power Mode menu, select the PoE mode in which the port must function:
802.3af: The port is powered in and limited to the IEEE 802.3af mode. A PD that
requires IEEE 802.3at does not receive power if the port functions in IEEE 802.3af mode.
Legacy: The port is powered using high-inrush current, which is used by legacy
PDs that require more than 15W to power up.
Pre-802.3at: The port is initially powered in the IEEE 802.3af mode and, before
75 msec pass, is switched to the high power IEEE 802.3at mode. Select this mode if the PD does not perform Layer 2 classification or if the switch performs 2-event Layer 1 classification.
802.3at: The port is powered in the IEEE 802.3at mode and is backward
compatible with IEEE 802.3af. The 802.3at mode is the default mode. In this mode, if the switch detects that the attached PD requests more power than IEEE
802.3af but is not an IEEE 802.3at Class 4 device, the PD does not receive power from the switch.
11.
From the Power Limit Type menu, select one of the following options:
None: The port draws up to Class 0 maximum power in low power mode and
up to Class 4 maximum power in high power mode.
Class: The port power limit is equal to the class of the attached PD.
User: The port power limit is equal to the value that is specified in the Power
Limit (W) field. This is the default setting.
Note: If a PD doesn't report its class correctly, these options can preserve PoE power
by preventing the switch from delivering more power than the PD requires. However, depending on which option you select, a PD that doesn't report its class correctly might now power up at all.
Note: Power Limit (W) displays a fixed power of 31.2 Watts, and you cannot change it.

12.
From the Detection Type menu, select one of the following options:
IEEE 802: The port performs a 4-point resistive detection. This is the default
setting.
4pt 802.3af + Legacy: The port performs a 4-point resistive detection, and if
required, continues with legacy detection.
Legacy: The port performs legacy detection.
13. Click the APPLY button. Your settings are saved.

Diagnostics and Troubleshooting

This chapter covers the following topics:
• Test cable connections
• Resolve a subnet conflict to access the switch
• PoE troubleshooting suggestions
86
Gigabit Ethernet Plus Switches

Test cable connections

You can use the cable diagnostic feature to easily find out the health status of network cables. If any problems exist, this feature helps quickly locate the point where the cabling fails, allowing connectivity issues to be fixed much faster, potentially saving technicians hours of troubleshooting.
If an error is detected, the distance at which the fault is detected is stated in meters. (This is the distance from the port.)
To test cable connections:
1. Connect your computer to the same network as the switch. You can use a WiFi or wired network connection, or connect directly to a switch that
is off-network using an Ethernet cable.
2. Launch a web browser.
3.
In the address field of your web browser, enter the IP address of the switch. The login window opens.
4. Enter the switch password. The password is the one that you specified the first time that you logged in. The user
name and password are case-sensitive.
The Home page displays.
5. Select Diagnostics > Cable Test.
6. Select one or more ports to test the cable that is attached to the port.
7. Click the NEXT button. The switch tests the cable connection for the selected ports and displays the results.
This process might take up to a few minutes.
8. Click the DONE button to dismiss the test results. You can run another cable test if desired.

Resolve a subnet conflict to access the switch

If you power on the switch before you connect it to a network that includes a DHCP server, the switch uses its own default IP address of 192.168.0.239. This subnet might
User Manual87Diagnostics and
Troubleshooting
Gigabit Ethernet Plus Switches
be different from the subnet used in your network. You might see the following message if you try to access the switch:
The switch and manager IP address are not in the same subnet.
To resolve this subnet conflict:
1. Disconnect the Ethernet cable between the switch and your network.
2. Shut down power to the switch.
3. Reconnect the Ethernet cable between the switch and your network.
4. Reapply power to the switch. The switch powers on. The network DHCP server discovers the switch and assigns
it an IP address that is in the correct subnet for the network.

PoE troubleshooting suggestions

Here are some tips for correcting Power over Ethernet (PoE) problems that might occur on switches that support PoE:
Make sure that the PoE Max LED is off. If the PoE Max LED is solid amber, disconnect
• one or more PoE devices to prevent PoE oversubscription.
Make sure that the Ethernet cables are plugged in correctly. For each powered
• device (PD) that is connected to the switch, the associated PoE port LED on the switch
lights solid green. If the associated PoE port LED lights solid amber, a PoE fault occurred and PoE halted because of one of the conditions listed in the following table.
Table 6. PoE fault conditions and possible solutions
Possible SolutionPoE Fault Condition
A PoE-related short circuit occurred on the port.
The PoE power demand of the PD exceeded the maximum level that the
switch permits. The maximum level is 15.4W for a PoE connection or
30W for a PoE+ connection.
The problem is most likely with the
attached PD. Check the condition
of the PD or restart the PD by
disconnecting and reconnecting
the PD.
The PoE current on the port exceeded the classification limit of the PD.
The PoE voltage of the port is outside the range that the switch permits.
Troubleshooting
Restart the switch to see if the
condition resolves itself.

Additional Switch Discovery and Access Information
This appendix provides additional information about how you can discover and access the switch in your network.
The appendix contains the following section:
• Access the switch from any computer
93
Gigabit Ethernet Plus Switches

Access the switch from any computer

This procedure requires you to use an IP scanner application. Such applications are available on the Internet, and some of them are free of charge.
To discover the switch IP address and access the switch from a computer:
1. From a computer that is connected to your network, run the IP scanner application in your network.
The IP address that is assigned to the switch displays in the IP scanner application.
Note: You can also access the DHCP server (or the router that functions as a DHCP server) in your network and determine the IP address that is assigned to the switch.
2.
Open a web browser, and in the address bar, type the IP address of the switch. The login page of the device UI opens.
3. Enter the switch password. The default password is password. The password is case-sensitive.
The HOME page displays.
The right pane (or, depending on the size of your browser window, the middle pane) shows the IP address that is assigned to the switch.
Tip: You can copy and paste the IP address into a new shortcut or bookmark it for quick access on your computer or mobile device. However, if you reboot the switch, a dynamic IP address (assigned by a DHCP server) might change and the bookmark might no longer link to the login page for the switch. In this case, you must repeat Step 1 through Step 3 so that you can discover the new IP address of the switch in the network and update your bookmark accordingly. You can also set up a fixed (static) IP address for the switch (see Set up a fixed IP address for the switch on page
15) to make sure that the new bookmark always links to the login page for the switch, even after you reboot the switch.
